What's new

Acronis Cyber Protect Cloud

Advanced Email Security: API-based inbound email scanning for Microsoft 365 users​

Reduces service delivery costs and increases scalability by onboarding new Microsoft 365 end customers more easily and quickly. The new API-based connectivity method shifts the management of protection scope from rules on the Microsoft 365 side to the Advanced Email Security console, thus reducing the configuration errors that typically occur during partial domain protection configuration.

Advanced Email Security: Outbound email scanning for Microsoft 365 users​

Enables partners to enhance protection while reducing service costs when outbound scanning is required. It also minimizes the risk of reputation damage by detecting malicious emails originating from the end customer's email service, and improves inbound protection accuracy by gaining a deeper understanding of communication with external parties.

Advanced Email Security: Updated insights dashboard​

Improves security related decision making by increasing visibility into the attack landscape. The updated insight dashboards now offer additional information on:

  • Top 5 attack types an end-customer experiences.
  • Highlighted attacks that the Incident Response [IR] team thinks you should be aware of.
  • List of attack types affecting the end-customer, along with explanations.
  • Metrics for the top attacked people, top compromised people, and top impersonated identities.

Advanced Email Security: Scan history view​

Improves efficiency of investigating the lifecycle of a scan-based detection.​ The new functionality provides information about a scan's lifecycle events (for example, scan time, release time) and includes all emails sent between the admin user and the Perception Point's MDR team.

Advanced Email Security: Management of restricted files types 

Improves protection via a customized restricted files policy for inbound emails and partners' self-service capabilities. Users can now view and manage the restricted files policy for an end-customer.

Advanced Management: Defining a status for script execution​

The improved UI ensures that when a script is created or cloned/restored, the script is ready for immediate use. This increases the efficiency of IT administrators.

Backup: Acronis Backup plugin for cPanel & WHM update 1.7.0

  • Supports additional operating systems that are gaining popularity among web hosting service providers: Ubuntu 20.04 LTS and Rocky Linux 8.​
  • Introduces a new logic of processing system databases to cover a wider range of non-typical database configurations available with MySQL 8.
  • Provides for hassle-free recovery of databases following the MySQL engine update after backup.

Management Portal and Platform Core

Enable services, packs, offering items for multiple tenants​

Saves time and money by eliminating the need to update individual tenants manually when a service, billing mode, advanced pack, or offering item needs to be enabled. All types of tenants are supported: partners, folders, customers.

Current limitations​:

  • Multiple selections limited to 100 tenants.
  • Supports only additive changes:
    • De-selecting services, editions, billing modes, or offering items won't disable them.
    • Switching editions is not yet supported for customers.
    • Modifying quotas is not yet supported.
